ASCA provides the Medicare Rate Calculator, a members-only resource that clearly and easily shows your Medicare payment rates for ASC-payable procedures. By selecting your state and county from the drop-down menus, the calculator automatically finds your local wage index and calculates the total payment, Medicare payment and beneficiary copayment for each procedure. The calculator is made available when new rates are released by the Centers for Medicare & Medicaid Services (CMS), most notably in the summer for the proposed payment rule and in the fall for the final payment rule. New calculators are also posted for regular quarterly updates, as well as any ad hoc updates to the payment rates at other times.
